NM51 you have a lot of duals! I was planning on running a dual master... preferably one that has the lines exit on the left side. Think I saw a post about one somwhere on this site.

I never heard of the 2 masters side by side. guess it makes sence fof safety... as long as the linkage doesn't fail.

If I look at a disc/ drum cylinder, will it already have the correct residual valves? If I run discs in the back and use the cadillac calliper with the cable break does that 2 lbs residual still remain true? I think the lower residual pressure is because of the return springs, but still confused about that.
